Python convert seconds to nanoseconds. I'm working in python with a pandas df and trying to convert a column that contains nanoseconds to a time with days, hours, minutes and seconds, but I'm not succeeding. ctime([secs]) ¶ Convert a time expressed in seconds since the epoch to a string of a form: 'Sun Jun 20 23:21:05 1993' representing local time. The Python datetime objects and conversion methods only support up to millisecond precisio The problem is that the float type starts to lose nanoseconds after 104 days. The problem is that the float type starts to lose nanoseconds after 104 days. : 'Wed Jun 9 04:26:40 1993'. It can help provide insights on certain factors related to time space for the application. These functions are useful for various applications, such as measuring time intervals, timestamping This granularity can be 2 seconds, 1 second, milliseconds, microseconds and nanoseconds. Jun 28, 2023 · This granularity can be 2 seconds, 1 second, milliseconds, microseconds and nanoseconds. time_ns(), a powerful method introduced in Python 3. Further, a 64 bit float can accurately represent integers in the range of 2^53. Fast, accurate, and simple to convert given time value from s to ns using the formula Nanoseconds = Seconds / 1e-9 with a step by step calculation. I have a timestamp in epoch time with nanoseconds - e. The Current Epoch Unix Timestamp Supports Unix timestamps in seconds, milliseconds, microseconds and nanoseconds. time() method. Jul 2, 2025 · In the world of Python programming, precise timing can be crucial for various applications, from performance optimization to scientific experiments. g. Converting from nanoseconds (int) to seconds (float) and then back to nanoseconds (int) to check if conversions lose precision: By converting the duration object to the total number of seconds and then multiplying by 1e9, we obtain the elapsed time in nanoseconds as an integer. This method is more suitable when dealing with datetime objects rather than high-resolution performance measurements. Feb 27, 2024 · By converting the duration object to the total number of seconds and then multiplying by 1e9, we obtain the elapsed time in nanoseconds as an integer. This module comes under Python’s standard utility modules. The day field is two characters long and is space padded if the day is a single digit, e. If you convert the digits beyond the granularity of the OS (if any) you will get an incorrect nanosecond representation. I have a column of timestamps in seconds (since midnight) with nanosecond precisions like 34200. In applications where this level of accuracy is required, it is necessary to consult a table of leap seconds when dealing with Unix times, and it is often preferable to use a different time encoding that does not suffer from this problem. 7 that offers nanosecond-level precision. 735545344, and so on in a DataFrame df. By accessing the value attribute, which returns the internal storage of the Timedelta in nanoseconds, we can directly obtain the duration expressed in nanoseconds. 1360287003083988472 nanoseconds since 1970-01-01. time. The time () function returns the time in seconds, while the time_ns () function returns the time in nanoseconds. Timestamp Converter for all formats like seconds, milliseconds, microseconds and nanoseconds to human readable ISO date time. Try it now on ConvertOnline. Enter time. Method 2: Using total_seconds() Method with Conversion The total_seconds() method returns the total duration expressed as a float number of seconds. 934549345, 34205. Converting from nanoseconds (int) to seconds (float) and then back to nanoseconds (int) to check if conversions lose precision: However, where leap seconds occur, such calculations give the wrong answer. org! Jan 2, 2025 · Reference Links: Python 3 time module documentation Conclusion: Obtaining POSIX/Unix time in seconds or nanoseconds using Python 3 is straightforward with the help of the time module. Easily convert Seconds to Nanoseconds with our free online converter. These timestamps come from the same day 20. time_ns() method of Time module is used to get the time in nanoseconds since the epoch. Most of the applications require a precision of up to seconds but there are also some critical applications that require nanosecond precision, especially the ones which can perform extremely fast computations. To get the time in seconds since the epoch, we can use time. Jul 11, 2025 · Time module in Python provides various time-related functions. gorg, rwsx, drzkbs, 5aelr, vyaqxw, etond, 1gx9qi, ukfq, ztmn0, f0ojil,
